My original post about Project Dunkelfeld stated that there are a great many men whose sexual orientation is towards children or young teenagers, but who are horrified by their urges. Project Dunkelfeld was started to treat these men, who were afraid to seek treatment themselves, fearing that they would be arrested even though they had never acted on their desires.
The paedophiles/hebephiles who do believe that children enjoy their attentions, who do not believe that children or young teenagers are traumatised, are much more likely to act on their desires. And, it might be, only come to treatment when forced to, because of having been arrested and sent to Jail.
Both kinds of paedophiles/hebephiles - the ones who are horrified by themselves, and the ones who think it's fine to act on their desires - need treatment.
The point that Project Dunklefeld made was that by treating the inactive men, it is preventative work. And apparently they have been quite successful in treating them. It's interesting that P Dunklefeld does quite a bit of social skills training.
I think (have no evidence) that the ones who are active, who have abused, who deny that what they do IS abuse, are much much harder to treat.
